"Andrew and his crew are fantastic. On time, knew what the issue was (fixed an issue from a different local HVAC Contractor did during install), and was extremely fair in pricing. Added an additional vent to my family room to help air circulation as well. Very professional company and will be calling Muller Mechanical from now on!"

I’ve been in the cleaning business for the last 15 years. I am 34 with two young children and really enjoy cleaning and organizing, making space for homeowners to feel more clear minded and less stressed.

"I can't say enough good things about this company. They promptly and fully repaired all of the detrimental and pointless "work" done by Peak Heating and got my boiler running efficiently before winter. The service reps were reliable, professional and knowledgeable. I highly recommend their work."

"I had got a estimate from a local hvac business cause they were in the area and I didn't know that fixed furnaces or center air . The first company came out and tried to sell me everything and anything and had financing .. I almost did it but the 12 thousand plus price tag scared me .I'm glad I didn't cause a guy at work gave me the number to MIKE at MCHVAC and I'm glad I called .Mike came out and gave me a honest professional option of what shape my system was in and option of what I could do . He replaced the central air system with even having to replace the furnace that was only 5 years old I might add .the first guy told me I pretty much had to buy all new cause it would work just replacing the central air .. Thank you Mike and MCHVAC for being honest and doing a awesome job. . MCHVAC SAVED ME OVER $7000 that I didn't need to spend . I give recommend Mike to all my family and friends ."

Heating and Air Conditioning questions, answered by experts

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.
