Fairfield Heating & Cooling was established in 1994 to provide economical comfort solutions to residential and commercial customers. In 1997, McGrew Inc., a local fifty- year-old heating & air conditioning company was purchased and its operations were combined with Fairfield Heating's operations. The combination of these two businesses now provides Fairfield and surrounding counties with one of the largest full service heating and air conditioning companies in the area. Since the inception of the business in 1994 there has been a focused approach to the core business of providing heating, air conditioning, and indoor air quality solutions for residential and commercial structures. By maintaining this focus we have been able to consistently provide modern and innovative approaches to our customers' needs.

"Took two service calls to find leak in condenser coil. Had to pay for service call, labor and new refrigerant even though the unit was under warranty. Only condenser coil was covered under warranty had to pay for parts and labor. Installation was estimated to take 3-4 hours . Actual installation time was 1.5 hours but I was still charged for 4 hours. I was reimbursed for the leaked refrigerant but not for the overcharge for labor. The unit is so far working well."

Heating Oil questions, answered by experts

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
