"I made an furnace inspection in a house I had purchased. Milo responded quickly and by the time he arrived (on time) my furnace had stopped working. He diagnosed the problem and fixed other other potential problems. He he was organized, compitent and friendly. He is coming back this week to install an air filter which the furnace lacked. We spent a cold night, but warmed up quickly after Milo arrived. Thank you for professional and friendly work."

"Hired West Mechanical to install a bathroom exhaust fan and light fixtures. Exhaust fan was left with duct disconnected and wiring exposed. Called Customer Service multiple times over 3-week period to get an estimate to reconnect the duct and address the wiring, still unresolved with open permit. UPDATE: I received a call from one of the company owners when he was made aware of the issue. He apologized for what I experienced and said it was very atypical for the company. He arranged to have an electrician complete the work the next day. The work included installation of a new duct transition that was not in the original scope, which was done at no charge. West Mechanical also sent a Supervisor the day after the work was completed to verify that the work was done to my satisfaction. Although I was unsatisfied earlier, I recognize that not every job will go as planned and I have been very impressed by how West Mechanical has responded. I would not hesitate to use them in the future."

"Northwest Home Repair responded immediately when contacted about a water leak that I couldn't locate, but could hear. Two technicians worked to finally locate the leak (unfortunately it was in the crawl space under my house) and a third plumber made the repair. I was informed up front of all costs. The repair was completed within 5-6 hours of my call even though the responding plumbers were almost 60 miles from my location on Whidbey Island. I HIGHLY recommend Northwest Home Repair Solutions...they are five star professionals! Kit McCartney"

Heating and Air Conditioning FAQs, answered by experts

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

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.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.
