"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

Heating and Air Conditioning questions, answered by experts

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

Installing a new AC unit costs $5,850 on average, but costs vary by the make and model, unit size, and unit type. Portable and window AC units cost between $90 and $550, which is significantly less than central or ductless AC systems. You’ll also have to pay for labor.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
