"Outstanding pricing and quick installation on a new heating and AC system. Installation of new equipment was clean and very professional looking. Justin in sales did an excellent job of listening to my concerns with the old system and proposing a new system to improve heating and cooling comfort in my home. Hvac technicians Vitaliy and Igor did a wonderful job of system installation and checkout. I could not have asked for a better experience."

"Mike and his associate, Andy, arrived on time and explained the process of the cleaning. Mike took before and after pictures, which showed us the extreme difference - we definitely got more than our monies worth! They were personable, professional and very affordable. Mike pointed out that we had a busted dryer vent that was causing some of the dryer lint to come into our home. We asked if he could repair it and he was able to do that. The whole process took about 1 1/2 hours, and we are totally enjoying the clean, fresh air whenever the furnace kicks in. We would hire Integrity Furnace again in a heartbeat, and would definitely recommend them to family and friends."

"I had my air conditioner cleaned and technician Eric B. was excellent! While waiting for my air conditioner to kick in he offered to fill my water softener with salt. I was so appreciative of this kind gesture and it reconfirmed why I chose to buy my new furnace and air conditioner from B&D!"

"Mike's men showed up in a timely window. Wanted to get right to work. They explained what they were going to do. Explained why things had to be done per code. I felt comfortable leaving them alone to cut the lawn. Very nice, clean, professional and quick. I would very highly recommend Mike's Monticello Plumbing to friends, family and strangers. Top shelf work. Cheers Mate."

Air Conditioning questions, answered by experts

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
