Can't say enough great things about Collin and Tech Air. Our 20+ year old AC went out in the middle of a heat wave. Found Collin/Tech Air and read 5 star review after 5 star review. He actually answered the phone himself and booked an appointment to come out the following afternoon. Got a call the very next day from Collin telling me he was in the area and could come by 3 hours early - he had the problem diagnosed in literally 5 minutes- had a ... continue reading

Colin and team were very professional and efficient. I received several bids and the only one that was less was one of those guys who does side jobs that may or may not be reliable down the road. As we all know, the last thing a homeowner needs is to be left holding the bag on a major part of your home, so it is great to have the assurance that Colin and his team will be there if things go wrong. From the workmanship however, it does not appear ... continue reading

Colin is very knowledgeable and professional. Our family is looking to make an upgrade to our HVAC system and to a system that is more energy efficient. Colin shared his product knowledge, system requirements and ideas for possible solutions in a manner which is easy to understand for a homeowner. I am also impressed by Colin's knowledge of local rebate programs and his recommendations based off these opportunities.

A great air conditioning system is your best energy saver!

Heating and cooling systems account for a large percentage of the energy used in homes across the country. In order to save money on your energy bills, it is important to have a good HVAC system that is properly installed and maintained. Once you have installed a good HVAC system, it is important to keep it well-maintained. A technician should inspect and clean your system on a regular basis, making any necessary repairs or adjustments. This will help keep your energy bills low and ensure that your system runs smoothly year round.

The Ins and Outs of Air Conditioning

Air Conditioners work by removing heat and humidity from the air inside your home, making it more comfortable to live in during hot weather. There are several types of air conditioners, including central air conditioners, window air conditioners, and portable air conditioners. Central air conditioners are the most common type of air conditioner, and they are usually used in homes with forced-air heating systems. Window air conditioners are less expensive than central air conditioners and can be installed in a window or through a hole in an exterior wall. Portable air conditioners can be moved from room to room and are typically used in rooms that are not used all the time, such as guest rooms.
When shopping for an air conditioner, it's important to consider the size of the unit, the fan speed, the energy efficiency rating, and the features that are important to you. You should also have a qualified HVAC technician size the air conditioner for your home to ensure that it is the correct size.

Energy Efficiency Guide for Heating & Cooling

  • Heat pumps are a great way to heat and cool your home, and they can be more energy efficient than other heating and cooling systems. A heat pump transfers heat from one place to another, either from the outdoors to your home or from your home to the outdoors. This makes them a good choice for heating and cooling your home, since they can use less energy than other heating and cooling systems.
    There are two types of heat pumps - air-source and water-source. Air-source heat pumps use the air outside your home to transfer heat, while water-source heat pumps use water from a lake, river, or underground well. Heat pumps are available in both gas and electric models. If you're considering a heat pump for your home, it's important to consult with a qualified HVAC technician to determine which type of heat pump is best for your needs.
  • Furnaces are used to heat homes with forced-air heating systems. A furnace heats air and blows it through a system of ducts to distribute the warm air throughout your home. There are several types of furnaces, including gas furnaces, oil furnaces, and electric furnaces. Gas furnaces are the most common type of furnace, and they use natural gas or propane to heat your home. Oil furnaces are less common than gas furnaces, but they can be a good choice for homes that do not have access to natural gas. Electric furnaces are the least common type of furnace, but they are a good choice for homes that do not have access to natural gas or oil.
    When shopping for a furnace, it's important to consider the size of the unit, the fuel type, and the energy efficiency rating. You should also have a qualified HVAC technician size the furnace for your home to ensure that it is the correct size.
  • There is no easy answer when it comes to deciding between electricity and gas. Both have their pros and cons when it comes to efficiency. Electricity is more expensive than gas, but it is also more efficient. Gas is less expensive than electricity, but it is not as efficient. Ultimately, the decision between electricity and gas depends on your needs and your budget.
    If you're considering switching to a gas furnace or heat pump, it's important to consult with a qualified HVAC technician to determine if your home is compatible with a gas-powered system.
  • There are many myths about heating and cooling systems, and how to save energy (and money) throughout the year as the seasons change. Contrary to popular belief, you don't have to keep your home hot in the summer or freezing during the winter to save on the energy bill! In fact, it's most energy efficient to use your furnace and air conditioner on a regular basis to maintain your home's comfortable temperature.
    In the winter months, use natural resources to your benefit! Open blinds and curtains to allow heat from the sun into your home, and keep your furnace at a steady, comfortable temperature. Of course, if you crank the heat up too high you will see a rise in your energy use, but steady comfortable temperatures won't break the bank - especially if you have a good HVAC system!
    Some homeowners believe that opening windows will help cool your home in the summer, when in fact, opening windows in the summer can make your home much hotter by letting in the surrounding air. The best way to keep your home comfortable in the summer is to keep the windows closed and the blinds or curtains drawn. This will help block out the sun's heat, and make your air conditioning most effective.
    Throughout the year, it's important to keep your HVAC system well-maintained and repair when needed. Maintenance and repair allows your system to function at its best, and be the most energy-efficient it can for your home.
