"ABCastello HVAC removed old A/C inside and outside units which were 25 years old from my 2700 sq feet 2 store colonial brick face house. Old units were replaced with new and more efficient units - TRANE 4 ton two stage SEER 17+ ECONET (condenser model RA-1748-AJ2CB, air handler model RH-2T-4821-MEACJA and communicating module Econet STAT model RETS-T601-SYS). Excellent work quality! Fast response! Very reasonable price quote for 10 years parts warranty and 5 years labor and service warranty! Honest and hard working person! All work was done in a couple of days (including old unit removal)! I am very happy and a very satisfied customer of his service for life!!! A+++++"

"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

Heating and Air Conditioning FAQs, answered by experts

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

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.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
