Causes of Low Cooling Levels in Your AC

Monday, April 25th, 2016

Oxford, MI experiences hot summers, which means you need your air conditioner to function as advertised at all times. Imagine your concern when you turn on the air conditioner for the first time all year, only to find that the air coming out of your vents isn’t especially warm. Low cooling levels in your air conditioner can stem from many sources, but now is the time to deal with them, before summer arrives in earnest and you need your system to work. Here’s a quick breakdown of possible causes: (more…)

Monday, March 21st, 2016

Spring has officially come to the Oxford, MI area, and while it may not feel like it now, the heat of summer will be here before you know it. Air conditioning systems are the best solution for beating the heat, but you want to make sure that the monthly cooling bills don’t squash you flat in the bargain. We have a few friendly tips to help boost air conditioning efficiency this summer, and hopefully spare you that pinch. Many of them can (and should) be planned for now, before the first heat waves of the year hit. (more…)

What Does Heat Pump Maintenance Entail?

Monday, July 14th, 2014

Heat pumps, like standard central air conditioners, require maintenance on a regular basis to help prevent unnecessary repair work and inefficient operation. Because a heat pump works throughout the year, either heating or cooling, it should have two regular maintenance sessions annually, one before the summer heat and one before the winter cold.

In most ways, heat pump maintenance is similar to air conditioning maintenance; heat pumps operate on the same principles as ACs, only with the ability to change the direction of heat exchange. When you call Davison Heating & Cooling for heat pump maintenance in Oxford, MI, you will receive the same quality treatment any air conditioner receives, with a few special steps that are particular to heat pumps.

What to expect from heat pump maintenance

First, we’ll look at the two ways that heat pump maintenance is difference from air conditioning maintenance:

  • Checking on the reversing valve. This component is the major mechanical difference between heat pumps and ACs, since it is what allows the heat pump to send refrigerant in different directions and therefore switch between heating and cooling. Maintenance makes sure that this valve is in good shape and not in need of replacement.
  • Condensate drainage check. Air conditioners also need checks on the condensate pans and drains that remove the excess moisture that drips from the evaporator coils. However, a heat pump has two sets of condensate drains, because both the indoor and outdoor coil at different times act as the evaporator coil.

Other than this, you can expect the same checks and adjustments for your heat pump as done during air conditioning maintenance:

  • Thermostat checks and recalibration.
  • See that the motors have sufficient lubrication and are not over working.
  • Clean or replace the air filter.
  • See that the refrigerant is at its proper level, and replace lost refrigerant if necessary.
  • Overview of the electrical system, including the amp draw on all the motors, with adjustments and tightenings for connections where needed.
  • Cleaning the indoor and outdoor coils.
  • Checking the fan blades for possible damage.
  • Blower assembly inspection.
  • Check that the compressor is operating at maximum efficiency.
  • Airflow check from all the vents.
  • Cleaning the outdoor condenser.

If the technician comes across any issue that will require larger repair work than basic adjustments and tune-ups, he or she will inform you of the problem and help you make arrangements for prompt repairs.

When you have your heat pump maintenance in Oxford, MI placed in the care of Davison Heating & Cooling, you will receive quality work from technicians with the experience necessary to make sure your heat pump operates at its best.

How to Prioitize Your Appliances for Generator Installation

Friday, June 20th, 2014

Spates of bad weather during the past ten years have reminded us that having an automatic standby generator for a home is no longer simply a luxury. When it’s possible to lose power for a number of days due to a blizzard, accident, or grid failure, it’s more than our comfort that’s under threat. A generator will not only protect the comfort and health of your family, it will also provide the peace of mind that you have everything necessary covered in the event of an emergency.

We realize that generators can be costly. Fortunately, you do not need to install a standby generator in your home that powers all its appliances. Instead, you can have a smaller unit put in (still bigger and more dependable than a portable unit) that powers only the appliances essential for your household’s health and safety. In this post we’ll look at how best to prioritize what you need to power in your home during an outage so you’ll know how best to size a generator.

Davison Heating & Cooling is here to help you with this important task. We specialize in automatic standby generator installation in Oxford, MI.

Priorities for your home’s appliances

  • Electrically powered medical equipment: For some families, the reason they want to have a generator installed in the first place is to ensure a steady electrical supply for members of their household who depend on powered medical equipment, like oxygen breathers and dialysis machines. If you need working medical equipment in your home, they should be the #1 priority for power.
  • Lights: Unless you have an enormous supply of candles, you will want some of your home’s lights to remaining burning. This is especially important if you have children or elderly people in your household, since poor lighting can be dangerous for them when they move around.
  • Heating system: Since many outages occur during winter, keeping your house warm is vital. Modern gas-powered heaters do require electricity to run (they use electrical igniters and fans), so no matter what type of heating system you use, you will need electrical power from a generator to keep it going during a power outage.
  • Refrigerator/freezer: If a power outage lasts for a stretch, it will be important to be able to keep food fresh in a refrigerator.
  • Air conditioning: Usually a lesser priority than the heater, although outages can occur during heat waves. If you live in an area susceptible to power failures due to heat waves, bump this up in priority.

These are the essentials to prioritize. At a lower tier are the dishwasher, clothes washer and dryer, microwaves, television monitors, and computers. You will have to decide which of these are most vital for you (it will vary for everyone) and use the information to help your installers pick the right sized generator for you. Contact us today to find out more.

When you call Davison Heating & Cooling for generator installation in Oxford, MI, you’ll receive quality help that will ensure the operational integrity of your generator when you need it most. 

Why Generator Sizing Matters

Tuesday, April 8th, 2014

Power-outages are one of life’s unpredictables. They can occur during storms and tornados, or they can happen on a calm but hot summer day. They can last for a few minutes, or they might stretch on for a few days. Preparation is the best way to deal with a sudden loss of power in your home, and the best way to make sure you are ready is with a whole-house generator that will back you up when the power goes down.

Portable generators, although excellent for camping or to store in a vehicle for emergencies, lack the power necessary to handle a home’s needs during outages. You should instead call professional installers to put in an automatic whole-house generator. Not only will they take care of the complicated process of connecting the large generator to your power system, but the technicians will also size it—one of the most important steps in generator installation.

Since 1998, Davison Heating & Cooling has installed generators in Oxford, MI that have kept the lights burning in many homes. Rely on us to size and install the automatic standby generator that will give you peace of mind all year.

The importance of sizing

Sizing means finding the generator with the power level that will meet your home’s needs without overpowering its abilities. Going too large or too small can have unfortunate consequences.

A generator that lacks the power level necessary for your homes electrical needs will only keep the electricity flowing for a short time. You may also experience low levels of power, with dimmed lights and appliances that won’t turn on.

Even worse is a generator that has too much power. When an oversized generator comes on, the surge in power can cause damage to circuit boards and appliances, burning out lights and permanently damaging precision equipment.

To help an installer size your generator, he or she will need to know about your electrical use and home size. You will also need to specify what appliances you want to operate in case of a power outage. You may only wish for the most vital equipment to keep working: a few lights, the refrigerator so food won’t spoil, heater and/or AC, the water heater, and any necessary medical equipment. Or you may wish to have the full comfort of your home available. The installer will factor all this into the sizing.

No worries with professional generator installation

Putting in a generator is supposed to give you peace of mind. You can start easing your worries with a call to a professional installer. With Davison Heating & Cooling, you can feel confident that the technicians on the job will locate the right sized generator for your home. For generators in Oxford, MI, look to the experts at Davison Heating & Cooling.

Why You Should Prefer Using Automatic Standby Generators

Wednesday, February 5th, 2014

Right now, we are going through one of the coldest winters in recent memory. There’s no better time to emphasize the importance of a whole-house back-up generator for your home: being caught without power during a heavy cold snap or a storm is not only inconvenient and uncomfortable, it can be dangerous, especially if there are people in your home who have special medical needs that require electrically-powered devices.

Our team at Davison Heating & Cooling takes your comfort and safety seriously. That’s why we offer installation of automatic standby generators in Oxford, MI to help you make it through potentially lengthy power outages. We can also repair or perform partial replacement on an existing system. If you don’t have a whole-house generator currently, we recommend you install an automatic standby model. If your current generator isn’t automatic, we suggest you schedule an upgrade

The Importance of an Automatic Standby Generator

Why do we place so much importance on having an automatic standby generator? Although a standard whole-house generator should take care of your power needs (provided you have it professionally sized and installed), an automatic model removes some of the hassles and dangers from the cold.

An automatic generator is connected to your electrical system in a way that detects when the power is running normally. An automatic transfer switch will disconnect your home safely from the power grid and start up the generator’s engine. (Most generators use natural gas from the municipal supply, although there are models that run from stored propane or diesel.) When the power supply to the grid comes back on, the automatic switch shuts down the generator and reconnects you.

This means that you won’t have to bundle up and march out into the cold or a heavy snowstorm, to fumble around with the equipment on the generator to start it up when the power shuts off. Aside from this convenience, an automatic generator is helpful if you aren’t home and the people in the house do not know the location of the generator or how to operate it, or if they are physically incapable of going outside to turn on the generator. It’s all taken care of: when the power goes out, the generator activates without interruption.

Schedule Generator Installation

As we mentioned above, a whole-house generator needs to be sized so it will match the power needs in your home. Too large, and it could cause electrical shorts; too small, and it won’t do you much good. For proper generator sizing and installation, rely on heating service experts in Oxford, MI. Davison Heating & Cooling is ready to help you keep your family safe this winter with automatic standby generator service. Give us a call today and schedule your next installation service.

The Differences Between Electric and Gas Furnaces

Friday, December 6th, 2013

One of the major advantages of furnaces that keep them competitive in the home heating market is their flexibility. Furnaces come in a huge array of sizes and types, and they can run from a variety of different fuels, so they can fit almost any home. The two most common energy sources for modern heaters are natural gas and electricity, both of which come from a municipal source straight into your home, making them much more convenient than propane or oil.

In this post, we will go over the differences between electric and gas furnaces, which may help you if you are currently considering having installation of one or the other. For more information about how a furnace in Oxford, MI can work for you, contact the experts at Davison Heating & Cooling. Our NATE-certified technicians have many years of experience working with all types of furnaces and other heating systems.

Electric vs. natural: battle of the furnaces

The two furnaces have the same heat delivery method: they distribute heated air using blower fans through ducts and into vents. It’s how they heat the air that makes them different.

  • Gas furnace: When the thermostat sends the signal to the heating system that it requires a higher temperature, a silicon nitride igniter activates gas-powered burners in the furnace. Jets ignite along the burner and creates a high temperature gas, which then enters a series of chambers known as heat exchangers. The metal of the heat exchangers rises because of the combustion gas, and fans then blow air in and over the hot metal, where the heat transfers to the air. The blower fans then take this hot air and send it into the ductwork.
  • Electric furnace: An electric-powered furnace starts up with an electric ignition. Instead of lighting gas-jets, the ignition powers up a series of heating elements, which consist of coils that glow hot as current courses through them. The more heat the thermostat calls for, the more of the heating elements will turn on. The air heated from these elements is then wafted through the vents.

Which is better?

It depends on your home. Obviously, if you don’t have a natural gas line, the electric furnace is the natural option—although you can sometimes have a gas line installed if there is a nearby source. Electric furnaces tend to have lower installation costs and are smaller than their gas-powered cousins. They also pose no risk of toxic gas leaks. On the other hand, natural gas costs less than electricity, so gas-powered furnaces are cheaper to run, and they tend to provide more effective heating.

For a more solid answer to the question of gas vs. electricity, you will need the advice of experts. Davison Heating & Cooling can help you make the choice, and then provide you with a superb installation of your new furnace in Oxford, MI.

Common Fireplace Repairs We Encounter

Wednesday, September 18th, 2013

Nothing makes your home feel cozy and warm in the wintertime like a good fireplace. Oxford, MI, with its cold winters and comparative isolation, has a large number of fireplaces, which augment furnaces and other heating systems with a little old-fashioned atmosphere. Not only are they romantic, but they can save you on heating bills as well. And when they need repairs, you want someone to deal with the matter promptly and professionally. Davison Heating & Cooling specializes in fireplace repair and can help you get yours back into shape before the snows of winter fall.

Here are just some of the common fireplace repairs we encounter.

  • Creosote build-up. When you don’t have enough draft in your chimney and your fireplace has glass doors or the like, your fire doesn’t burn as hot. This can create a build-up of creosote in the chimney, which is a problem because creosote is extremely flammable. It needs to be cleaned out of the chimney periodically in order to eliminate the risk of a fire (the wrong kind of fire).
  • Smoke pouring into the house. A functioning fireplace should draw smoke up into it naturally. When that doesn’t happen – and it doesn’t stem from an obvious issue like the damper being accidentally left closed – there’s likely a problem in need of fixing. Most of the time, there’s some kind of blockage in the chimney, such as leaves or birds’ nests left over from the summer. In some cases, it may indicate a more serious repair: damage to the chimney itself or a flue that isn’t properly sized.
  • Gas problems. Gas-powered fireplaces use natural gas to help start and/or continue a fire. If there are problems with the gas flow, either due to a leak or because the gas is cut off entirely, it prevents you from using the fireplace completely. (Never start a fire in a fireplace with a faulty gas line.)

If you experience these or any other problems, don’t hesitate to give Davison Heating & Cooling a call. We can identify the problem quickly and set up a scheduled visit to repair the fireplace in your Oxford, MI home. We have the solution for all manners of common fireplace repairs we encounter.
